In response to this need, today we launched a new Windows storage platform: Windows Unified Data Storage Server 2003 (WUDSS.) This new product – available now within Dell’s new PowerVault NX1950 hardware and through other OEMs later – represents a big milestone for Microsoft storage technology. By bringing together Windows Storage Server file server capabilities, Windows iSCSI target and initiator software, and new storage management features, WUDSS will be an ideal mid-range solution for customers looking to more easily store and manage file and block (email, database, line of business applications) data. WUDSS is great progress on our overall goal of making high end storage capabilities more affordable and accessible to a broader market.

Per the press release linked above:

Windows Unified Data Storage Server 2003 is a new Microsoft storage platform providing an advanced file server and IP SAN (iSCSI) capabilities, as well as unified management tools for easy deployment and maintenance in heterogeneous environments.

Think of WUDSS as an easier to use version of Windows Storage Server. I expect it has a different (and presumably lesser) price point too, but that wasn’t specified.
